I've merged a few of the threads covering this one.
Advice we've received:
"Samsung is aware of this phenomenon which may appear on Galaxy devices due to Google Webview issue and this problem was already resolved with the latest app updates of Android System Webview and Chrome, 89.0.4389.105 version."
To update Android System Webview
Settings >Apps > Search Webview > Tab Android System Webview > App details in store > Update.
To update Google Chrome

Please note that If the Update menu is not available, please tap the Enable button to activate app update.
